New Self-Rewarding Language Models Improving AI Training
Supercharging AI models requires superior feedback to train them effectively. Traditionally, AI models have been trained using fixed reward models derived from human preferences, which can limit learning during Large Language Model (LLM) training. This makes it difficult to advance AI agents beyond human performance. But recent research shows that leveraging human preference data can significantly enhance LLMs’ ability to follow instructions effectively.
Challenges in Traditional Methods
Traditional Reinforcement Learning from Human Feedback (RLHF) typically involves learning a reward model from human preferences, then using that fixed model for LLM training. Newer approaches like Direct Preference Optimization (DPO) skip the reward model training step and use human preferences directly for training. However, both approaches face limitations based on the scale and quality of human data available.
New Approach – Self-Rewarding Language Models
Researchers from Meta and New York University have proposed a new approach called Self-Rewarding Language Models to overcome these limitations. This method involves training a self-improving reward model that continuously updates during LLM alignment, integrating instruction-following and reward modeling into a single system.
Training iterations of Self-Rewarding Language Models have shown substantial performance gains, outperforming prior iterations and baseline models. These models have demonstrated competitive performance, surpassing existing models with proprietary alignment data, and enhancing instruction following and reward modeling abilities across iterations. This new approach presents a promising avenue for self-improvement in language models, moving beyond traditional human-preference-based reward models in language model training.
